Hi,
I'm trying to get a UITableView to read it's data from a file. I've attempted it like this:
NSArray *paths = NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullFileName = [NSString stringWithFormat:@"%@/entries.plist", documentsDirectory];
self.dataForTable = [[NSMutableArray alloc] initWithContentsOfFile:fullFileName];
This compiles fine, but when saving something to the file in the following snippet, the file is not saved nor anything is written to the array:
NSMutableDictionary*userDictionary;
userDictionary = [[NSMutableDictionary alloc] init];
[userDictionary setObject:name.text forKey:@"name"];
[userDictionary setObject:email.text forKey:@"email"];
[userDictionary setObject:serial.text forKey:@"serial"];
[userDictionary setObject:notes.text forKey:@"notes"];
[userDictionary setObject:[NSNumber numberWithInt:[licenseType selectedRowInComponent:0]] forKey:@"license_type"];
[userDictionary setObject:[date date] forKey:@"date"];
[userDictionary setObject:[NSNumber numberWithBool:[paymentSwitch isOn]] forKey:@"payment"];
NSString*dirToSaveTo = [NSHomeDirectory() stringByAppendingPathComponent:@"Documents"];
NSString*fileName = [NSString stringWithFormat:@"%@.plist",name.text];
NSString*saveName = [dirToSaveTo stringByAppendingPathComponent:fileName];
[userDictionary writeToFile:saveName atomically:NO];
NSArray *paths = NSSearchPathForDirectoriesInDomains
(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *fullFileName = [NSString stringWithFormat:@"%@/entries.plist", documentsDirectory];
[self.dataForTable addObject:name.text];
NSLog(@"%@",self.dataForTable);
[self.dataForTable writeToFile:fullFileName atomically:YES];
The NSLog just returns (null). The *plist file is never written. What am I doing wrong?
